1 24.9 Keeping track of available passes
1 ======================================
1
1 When your plugin is loaded, you can inspect the various pass lists to
1 determine what passes are available. However, other plugins might add
1 new passes. Also, future changes to GCC might cause generic passes to
1 be added after plugin loading. When a pass is first added to one of the
1 pass lists, the event 'PLUGIN_NEW_PASS' is invoked, with the callback
1 parameter 'gcc_data' pointing to the new pass.
